Abstract
This article presents the results of a study of a class of error-correcting codes called partial-unit-memory convolutional codes, or PUM codes for short. This class of codes, though not entirely new, has until now remained relatively unexplored. This article shows that it is possible to use the well-developed theory of block codes to construct a large family of promising PUM codes. Indeed, at the end of the article the performances of several specific PUM codes are compared with that of the Voyager standard (2, 1, 6) convolutional code. It was found that these codes can outperform the Voyager code with little or no increase in decoder complexity. This suggests that there may very well be PUM codes that can be used for deep-space telemetry that offer both increased performance and decreased implementational complexity over current coding systems.
